how can i copy line with text and image to ms word

If you want copy formatted text and image to MS Word, you need to give MS Word rtf markup, because Word can recognize rtf markup but not TLF markup.

So you need to create a custom clipboard to paste a rtf markup. It's a large feature for you, because you need a tlf-rtf converter in your custom clipboard.

TLF Custom Clipboard Example:

package
{
    import flash.display.Sprite;
    import flash.desktop.ClipboardFormats;
   
    import flashx.textLayout.container.ContainerController;
    import flashx.textLayout.conversion.ITextImporter;
    import flashx.textLayout.conversion.TextConverter;
    import flashx.textLayout.edit.EditManager;
    import flashx.textLayout.elements.*;
    import flashx.undo.UndoManager;
   
   
    // Example code to install a custom clipboard format. This one installs at the front of the list (overriding all later formats)
    // and adds a handler for plain text that strips out all consonants (everything except aeiou).
    public class CustomClipboardFormat extends Sprite
    {
        public function CustomClipboardFormat()
        {
            var textFlow:TextFlow = setup();
            TextConverter.addFormatAt(0, "vowelsOnly_extraList", VowelsOnlyImporter, AdditionalListExporter, "air:text" /* it's a converter for cliboard */);
        }
       
        private const markup:String = '<TextFlow whiteSpaceCollapse="preserve" version="2.0.0" xmlns="http://ns.adobe.com/textLayout/2008"><p><span color=\"0x00ff00\">Anything you paste will have all consonants removed.</span></p></TextFlow>';
        private function setup():TextFlow
        {
            var importer:ITextImporter = TextConverter.getImporter(TextConverter.TEXT_LAYOUT_FORMAT);
            var textFlow:TextFlow = importer.importToFlow(markup);
            textFlow.flowComposer.addController(new ContainerController(this,500,200));
            textFlow.interactionManager = new EditManager(new UndoManager());
            textFlow.flowComposer.updateAllControllers();
            return textFlow;
        }
    }
